ENGINE.

Application filed May 28,

This invention relates to improvements in internal combustion motors,the general object of the invention being to provide coneshaped valvesfor the motor for increasing the effectiveness of the same.

Another object of the invention is to provide reciprocating rodsoperated by cams and having means thereon for rotating the valves.

This invention also consists in certain other features of constructionand in the combination and arrangement oi? the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a side view of a motor constructed in accordance with this invention.

Figure 2 is a plan View.

Figure 3 is a section on line 3-3 of Figure 2.

Figure 4 is a section on line H of Figure 2.

In these views 1 indicates the body of the engine and 2 indicates thecylinders therein. The head 3 of the engine is provided with cone-shapedvalve seats 4 which are formed with a plurality of ports 5 whichcommunicate with the passages 6. A cone-shaped valve 7 engages eachvalve seat, each valve having a plurality of ports 8 for cooperatingwith ports 5 in the valve seat. The stem 9 of each valve passes throughthe head and projects above the same, the projecting part having a ballbearing 10 at its upper end which engages the upper end of a coil spring11, the lower end of the spring bearing against the head. This springacts to hold the valve against the seat. Each valve is adapted to berotated by means of a push rod 12 which has rack teeth 13 thereon forengaging teeth 14 on the valve stem. A cam 15 engages each end of eachpush rod and the cams are placed on shafts 16, these shafts beingconnected by the gears 17 with a shaft 18, which is driven 1923-. SerialNo. 642,020.

in any suitable manner from the crank shaft. The push rods are enclosedin housings 19 and the parts may be lubricated by forcing oil throughthe oil passages 20 in any suitable manner.

There may be two valves to each cylinder, one valve being an. intakevalve and the other an exhaust valve or I may provide a pair of inletvalves and a pair of exhaust valves for each cylinder as shown in thedetail views. In this case the spark plug 21 is located in the center.By rotating the valves the ports will be opened and closed will beunderstood so as to control the inlet an d exhaust. By using a largenumber of ports the effectiveness of the motor will be increased. Thesevalves also eliminate grinding and they are free from vibration.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall Within the scope of the appended claim.

What I claim is V In an internal combustion engine, a plurality ofcylinders, a pair of cone-shaped valve seats in the head of eachcylinder, each seat having a plurality of ports, a pair of hollowcone-shaped valves having ports registering with those of the valve seatseated in the said seats, a stem integral with each valve respectivelyextending up through the head, a washer carried on the end of the stemby a cotter pin, a ball bearing race carried on the stem bearing againstthe washer, a coil spring carried on the stem bearing against thebearing race and the top of the cylinder head, thereby holding the valveon its seat, a cap fitting over the projecting end of each stem andenclosing the spring and the ball bearing and fitted to a part of thecylinder head and a means for turning the valve.

In testimony whereof I affix my signature.

JULIUS A. KUSKE.
